Be it known that 1.,T1-rotms F. MULoArrnY,

citizen of the United States, residing at Colfax, in the county of McLean and State of lllmois, have invented new and useiul Improvements in Attachments for Motor-- Vehicle lVheels,of which'the following is a specification. I

I This invention relates generally to attachments for the wheels oi motor vehicles,

and particularly to means for maintaining anti-slip devicesuponthe'said wheels The primary object of the invention is to a 1 provide means whereby 'antl-skid chains or mud hooks maybe readilyan deasily ap plied to or removed from the wheel of the vehicle regardless of wl1ether the wheel may be immersed in a mud hole or upon firm ground, and wherein the trouble and labor incident to the applicationof the now generally used tires and mud hooks to a wheel is entirely dispensed with.

A further object of the invention. is to provide means'of the character and ior the purpose stated, by the use of which the strains incident to the engagement of the anti-slip device with the ground will be transmitted wholly to the parts of the wheel most able to withstand such pressures, and whereby danger of injury to the tire incis dent to the use of such anti-skid devices is almost entirely eliminated.

With these and other objects in view,,the

: invention consists of the features of conand rim of the wheel and-illustrating the means in which the chain engaglng rims are attached to the wheel,

Figure 3 is a detail perspective view of one of the clamp irons, and

Figure 47 is a sectional view illustrating the manner in which the rim'ends are secured together.

Referring now more particularly to the drawing, 5 indicates generally the telly of thevehicle wheel and 6 the spokes thereof.

tire 7 is employed,however,'it will be under stood that the invention may equally as well be carried out with solid or v-cushiontire wheels.

Arranged upon the inner and outer sides of the wheel andagainst the spokes thereof 1 are rings, runs or, bends lndicated at 8, the

latter being disposed concentrically with the- 1 rim 5 of the wheel and of slightlyv less diami eter than the same; One of the bands or I rings 8 is arranged upon each side ofthewheel,'and'these bands are preferably of the same diameter. ,The bands may be formedof any suitable metal of sufiicie'nt strength to withstand thestrains to which the 'mud' griprdevices must'necessarily be subjected i in use, and these rings or-bands may be made i of one piece of metal or may be'of they open ring type and provided at their adjacent ends with means for coupling 'thesame to- In the'present instance, the ex'-'v gether. tremities of the open rings are threaded as shown in Figure 4, and an internally threaded coupling sleeve 9 is employed to connect these ends together.

The bands or rings 8 are firmly held to'the wheel by means of clamp irons indicated at 1.0. These clamp members provide base por tions 11 and ring engaging portions. 12,

and the base portionsvll are provided with F apertures 18 through which bolts 14 are to be extended in attaching the clamp irons to "1 j the wheel; These clamp irons will be arranged in pairs; a pair for each spoke of the wheel," and the irons of each pair are dis- ,posed one upon each side of the adjacent spoke. The bolts 14 extend from one clamp iron to the other of each'pair and when the nuts are tightened upon said bolts the said irons will be drawn toward each other so as to cause the rings held in the portions 12 so that any strain imparted to the rings 8.-

will be borne almost entirely by the said telly.

The anti-skid devices used in the present instance comprise relatively short lengths of chain 15, sufliciently long to pass around the tire transversely, and the extremities of these chain lengths maybe provided with fastening devices of a simple nature, such as snap hooks indicated at 16.

In practice, the drive wheels of the vehicle i are provided each with a pair of the rings or chains 8 in the manner above described, and it Will be understooo that-When the various clamp irons are properly attached as abovespecified, these rings will be rigidly held to the Wheel. It is in ended that these rings be at all times m n uned upon the Wheel. Should it be required to apply anti-skid devices to the Wheel, they are applied to the tire thereof with the ends firmly secured to the said rings. 8. Any number of these grip members or chains may be applied to the Wheel, as Will vbe understood.

In instances Where the Wheel of the vehicle 18 zburiedin a mud hole or rut 1n the road and it desired to ap y oe anti-slzid devices thereto, this application may v be quickly made by applying the chains to tl at part of theevheel which is exposed, and'aiter the Wheel has been turned that part previously buried beneath the surface will be ez'posed and the grip members may bethen applied thereto.

it is apparent. that by this method the trouble and labor incident to the application of thenow generally used chains upon motor vehicle Wheels is entirely dispensed with,

and by my method the anti-skid chains or grip devices may be applied to Wheels Where heretofore it \VfLSiHlPOSSiblG to employ the ordinary chains as now used.

While the above is a description of the invention in its preferred form, it is to be understood that various changes in the details of construction and arrangment may be resorted to ifdesired, Without departing from the spirit of the invention is defined by the claim. l 7

Having thus fully described my invention,
